Patent number: 9581749Abstract: In a scan system, a lighting unit, a display, and a three-dimensional display that have all of high luminance, low power consumption, and high reliability of a circuit board are provided. A light modulation device bonded to a light guide plate is provided with a light modulation layer exhibiting scattering property or transparency to light propagating through the light guide plate. The light modulation layer is interposed between a lower electrode that is configured of a plurality of partial electrodes extending in a direction parallel to a light incident surface and a sheet-like upper electrode. A drive circuit sequentially drives the plurality of partial electrodes to scan a region exhibiting the scattering property of the light modulation layer in a direction orthogonal to the light incident surface.Type: GrantFiled: December 8, 2011Date of Patent: February 28, 2017Assignee: Sony CorporationInventors: Kentaro Okuyama, Makoto Shinoda, Shinpei Nagatani, Yuji Takahashi, Tomoaki Suzuki, Shogo Shinkai, Akira Ebisui, Taizo Nishimura

Patent number: 6796657Abstract: A projection type display apparatus including an illumination optical system for emitting a light flux, a decomposition optical system for decomposing the light flux into color lights of red, green and blue, liquid crystal light valves for the colors for receiving the decomposed color lights, a synthesis optical system for synthesizing the image lights of the colors from the liquid crystal light valves, and a projection optical system for projecting the synthesized image lights to a screen. A filter is disposed at one of positions opposing to each other across the center of the light flux between the white light source and the decomposition optical system and attenuates or cuts off light of a wavelength region different from that of light which passes the other of the positions.Type: GrantFiled: December 27, 2002Date of Patent: September 28, 2004Assignee: Sony CorporationInventors: Makoto Shinoda, Kenji Sugihara

Publication number: 20030151724Abstract: A projection type display apparatus which can maintain a high contrast for a long period of time and can be produced simply and at a low cost. The display apparatus includes an illumination optical system for emitting a light flux, a decomposition optical system for decomposing the light flux into color lights of red, green and blue, liquid crystal light valves for the colors for receiving the decomposed color lights, a synthesis optical system for synthesizing the image lights of the colors from the liquid crystal light valves, and a projection optical system for projecting the synthesized image lights to a screen. The first optical path from the illumination optical system to one of the liquid crystal light valves for a predetermined one color through the decomposition optical system is formed longer than second optical paths to the liquid crystal light valves for the other two colors.Type: ApplicationFiled: December 27, 2002Publication date: August 14, 2003Inventors: Makoto Shinoda, Kenji Sugihara

Patent number: 6559900Abstract: In a projection type display apparatus that projects an image by inputting a light beam emitted from a light source to a spatial light modulation device, it is intended to provide a lens array as a component of an illumination optical system that is low in manufacturing cost, provides high screen illuminance, and enables miniaturization of the projection type display apparatus. The dimension of the cell lenses of a second lens array is not uniform in one of the row direction and the column direction. Since the cell lenses are rectangular when viewed from the front side, the second lens array can be manufactured with a metal mold having a simple shape. The boundary lines between the cell lenses are straight and level differences at the boundary lines are small, sink marks of the second lens array are small, and the efficiency of utilization of light beams is high.Type: GrantFiled: January 11, 2000Date of Patent: May 6, 2003Assignee: Sony CorporationInventors: Tatsuru Kanamori, Makoto Shinoda, Tohru Kawai, Kenji Sugihara

Patent number: 6365526Abstract: An optical illumination system wherein an increased amount of light from a light source can reach a light valve, in which a luminous flux of the light source is irradiated upon a first lens array. The luminous flux having passed through the first lens array is introduced to the polarization conversion system provided immediately before a second lens array, and a luminous flux coming out from the polarization conversion system is introduced to the second lens array and then irradiated upon the light valve. The first lens array has an image forming position f which satisfies S<f<L where L is an optical path length of a longer one of optical paths of P polarized light and S polarized light decomposed from the luminous flux from the light source by the polarization conversion system and S is an optical path length of a shorter one of the optical paths.Type: GrantFiled: October 13, 2000Date of Patent: April 2, 2002Assignee: Sony CorporationInventors: Tatsuru Kanamori, Kenji Sugihara, Koji Kita, Makoto Shinoda
